-## Opensource & Contribution 
+## 🌟 What is NanoKVM?

-### Update 2025.02.14
-Newest APP v2.1.6 add most security enhancements&bug fix, recommend regular users upgrade to this version or newer.
+NanoKVM is a series of compact, open-source IP-KVM devices based on the LicheeRV Nano (RISC-V). NanoKVM allows you to remotely access and control computers as if you were sitting right in front of them – perfect for managing servers, embedded systems, or any headless machine.

-### Update 2025.02.05
-For users concerned about security, you can read this issue: https://github.com/sipeed/NanoKVM/issues/301 , you will find explanations addressing all security concerns.
-GitHub, as an open and transparent platform, provides a space for discussing so-called "backdoor" concerns. Open-source makes products more secure!
+## 📦 Product Family

-### Update 2024.10.18
+We offer several NanoKVM versions to suit your needs:

-We have opensourced the backend code in 10.8, and thank you for Civil PR it immediately, we will give you newest NanoKVM-PCIe as a reward！   
-The mid-Oct batch is starting testing and packaging, most order before 10.1 will ship out next and next next week.   
-The aliexpress shipping date is change to Dec since 10.1, it is a conservative delivery time. the order in Oct. should send out during 11.15~12.15.   
+* **NanoKVM-Cube Lite:** A barebones kit for DIY enthusiasts and enterprise users requiring bulk deployment.
+* **NanoKVM-Cube Full:** A complete package featuring a sleek case, accessories, and a pre-flashed system SD card. Ready to use out-of-the-box; ideal for individual users.
+* **NanoKVM-PCIe:** A unique form factor with a PCIe bracket for internal chassis mounting. It draws power directly from the PCIe slot and supports optional WiFi and PoE functions.

+## 🔩 Hardware Platform (NanoKVM Cube/PCIe)

-NanoKVM is based on Sipeed [LicheeRV Nano](https://wiki.sipeed.com/hardware/zh/lichee/RV_Nano/1_intro.html)，you can find specifications, schematics, and dimensional drawings [here](http://cn.dl.sipeed.com/shareURL/LICHEE/LicheeRV_Nano).
+NanoKVM is based on Sipeed [LicheeRV Nano](https://wiki.sipeed.com/hardware/zh/lichee/RV_Nano/1_intro.html). You can find specifications, schematics, and dimensional drawings in the [download station](http://cn.dl.sipeed.com/shareURL/LICHEE/LicheeRV_Nano).

 The NanoKVM Lite is constructed by the LicheeRV Nano and HDMItoCSI board, and the NanoKVM FULL adds the NanoKVM-A/B board and shell to the NanoKVM Lite. The HDMItoCSI board is used to convert the HDMI signal; NanoKVM-A, including OLED, ATX control output (USB Type-C interface), auxiliary power supply and ATX power on/off and reset buttons; The NanoKVM-B is connected to the plate at one end and the computer at the other end is connected to the computer ATX-Pin, which is used to remotely control the power of the computer.

 The NanoKVM image is built on LicheeRV Nano SDK and MaixCDK, and is compatible with materials that use the LicheeRV Nano, opposite the KVM software cannot be used with the LicheeRV Nano or other SG2002 products. If you would like to build an HDMI input application on LicheeRV Nano or MaixCam, please contact us for technical support.

-Note: Out of the 256MB memory in SG2002, 158MB is currently allocated for the multimedia subsystem, which NanoKVM will use for video image acquisition and processing

-スターが2Kに近づいています！10月中旬にバックエンドのソースコードを整理してオープンソース化します！（また、10.1前のすべての予約注文が出荷される時期でもあります）
-
-### 10.18 更新
-
-10.8にバックエンドコードをオープンソース化しました。すぐにPRを提出してくれたCivilに感謝します。最新のNanoKVM-PCIeを報酬として提供します！
-10月中旬のバッチはテストとパッケージングを開始しており、10.1前のほとんどの注文は次週と次々週に出荷されます。
-10.1以降、アリエクスプレスの出荷日は12月に変更されました。これは保守的な納期です。10月の注文は11.15〜12.15の間に発送される予定です。

-## ハードウェアプラットフォーム NanoKVM
-
-NanoKVMはSipeed [LicheeRV Nano](https://wiki.sipeed.com/hardware/zh/lichee/RV_Nano/1_intro.html)に基づいており、仕様、回路図、寸法図は[こちら](http://cn.dl.sipeed.com/shareURL/LICHEE/LicheeRV_Nano)で確認できます。
-
-NanoKVM LiteはLicheeRV NanoとHDMItoCSIボードで構成され、NanoKVM FULLはNanoKVM LiteにNanoKVM-A/Bボードとシェルを追加しています。HDMItoCSIボードはHDMI信号を変換するために使用されます。NanoKVM-AにはOLED、ATX制御出力（USB Type-Cインターフェース）、補助電源供給およびATX電源オン/オフおよびリセットボタンが含まれています。NanoKVM-Bは一端がAボードに接続され、他端がコンピュータのATXピンに接続され、コンピュータの電源をリモートで制御します。
-
-NanoKVMイメージはLicheeRV Nano SDKおよびMaixCDKに基づいて構築されており、LicheeRV Nanoを使用する資料と互換性があります。逆に、KVMソフトウェアはLicheeRV Nanoや他のSG2002製品では使用できません。LicheeRV NanoやMaixCamでHDMI入力アプリケーションを構築したい場合は、技術サポートを受けるためにお問い合わせください。
-
-注：SG2002の256MBメモリのうち、現在105MBがマルチメディアサブシステムに割り当てられており、NanoKVMはビデオ画像の取得と処理にこのメモリを使用します。

-## NanoKVM 硬件平台
-
-NanoKVM 基于 Sipeed [LicheeRV Nano](https://wiki.sipeed.com/hardware/zh/lichee/RV_Nano/1_intro.html) 核心板搭建，这部分硬件的规格书、原理图、尺寸图等均可在这里找到：[点击这里](http://cn.dl.sipeed.com/shareURL/LICHEE/LicheeRV_Nano)
-
-NanoKVM Lite 由 LicheeRV Nano E 和 HDMItoCSI 小板构成，NanoKVM FULL 在 NanoKVM Lite 基础上增加 NanoKVM-A/B 板和外壳。HDMItoCSI板用于转换HDMI信号；NanoKVM-A 包含 OLED、ATX控制输出（TypeC接口形式）、辅助供电（TypeC接口）以及ATX开关机、复位按键；NanoKVM-B 一端连接A板，一端连接电脑ATX针脚，用于电脑的远程开关机。
-
-NanoKVM 镜像在LicheeRV Nano SDK 和 MaixCDK 基础上构建，可以兼容使用 LicheeRV Nano 的资料，反之LicheeRV Nano 或其他 SG2002 产品无法使用KVM软件。如果您想在 LicheeRV Nano 或 MaixCam 上构建 HDMI输入相关应用，请与我们联系，以获得技术支持。
-
-注: SG2002的256MB内存中, 目前划分105MB用于多媒体子系统, NanoKVM会在视频图像采集和处理中使用这部分内存.
